Of course, the code doesn`t fail, but I also doesn`t get the new menu,

If the code is working, I`ll do all these changes to be able to detect
all different languages.

if I add these following lines to the code, I`ll get the actual menu
from the latest loaded dll!

void CMainFrame::OnLanguage(UINT nId)
{
  theApp.m_LanguageSupport.OnSwitchLanguage(nId); // Creates the
languages sub-menu

    CMenu* m_pMenuNew = new CMenu;
    m_pMenuNew->LoadMenu(IDR_MAINFRAME);
    SetMenu(m_pMenuNew);
}

But which additional steps do I have to do to get the latest dialog
box from the latest loaded dll file?
